Without computing, decide which symbol (>, <, or =) should be placed in the circle. Explain.

4 × 5 × 7 🔘7 × 4 × 2

• <; The first factor on the left is 4, the first factor on the right is 7, and 4 < 7.

• >; The last factor on the left is 7, the last factor on the right is 2, and 7 > 2.

• =; The factors in each expression are the same. The same factors grouped in a different way have the same product.

• >; The factors can be regrouped to show 4 × 7 × 5 on the left and 4 × 7 × 2 on the right. 4 × 7 is the same on both sides, and 5 > 2.

For the camp picnic, Kara buys 8 packages of hot dog buns with 6 buns in each package. She also buys 6 packages of hamburger buns with 8 buns in each package. Without computing, explain how the number of hot dog buns compares to the number of hamburger buns.

• The number of hot dog buns is greater than the number of hamburger buns. Kara buys 8 packages of hot dog buns and 6 packages of hamburger buns, and 8 > 6.

• The number of hot dog buns is greater than the number of hamburger buns. 8 × 8 > 6 × 6 because both factors on the left are greater than both factors on the right.

• The number of hot dog buns is the same as the number of hamburger buns. Using the Commutative Property, 8 × 6 = 6 × 8.

• The number of hot dog buns is less than the number of hamburger buns.  There are 6 hamburger buns in each package and 8 hot dog buns in each package, and 6 < 8.
